本文介绍了Spring CrudRepository在自定义查询方法定义上抛出AbstractMethodError的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试在扩展CrudRepository接口的接口中创建自定义查询。不幸的是，每次收到java.lang.AbstractMethodError时都会出于某些原因。请参阅下面的完整堆栈跟踪。
据我所知，问题是Spring框架应该神奇地为我的方法声明创建一个实现，但由于某种原因它不能实现它。
I'm trying to create a custom query in an interface which extends the CrudRepository interface. Unfortunately for some reason every time I receive a java.lang.AbstractMethodError. Please see the full stack trace below.
As far as I understand, the problem is that Spring framework should "magically" create an implementation to my method declaration, but for some reason it doesn't make it.
存储库界面：
public interface PresentationRepository extends CrudRepository<Presentation, Integer> {
Iterable<Presentation> findAll(Sort sort);
Page<Presentation> findAll(Pageable pageable);
List<Presentation> findByTitle(String title); // the problematic line
}
演示文稿类：
@Entity
@Table(name = "presentation")
public class Presentation {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "presentation_id")
Integer id;
String title;
String logo;
@Column(name = "length")
Integer interval;
@Column(name = "pages")
Integer pageCount;
Date created;
Date modified;
Date approved;
Date published;
Date deleted;
@ManyToMany(fetch = FetchType.EAGER)
@JoinTable(
name = "presentation_filters",
joinColumns = @JoinColumn(name = "presentation_id"),
inverseJoinColumns = @JoinColumn(name = "filter_id")
)
List<Filter> filters;
public Presentation() {
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
// OTHER GETTERS AND SETTERS FOR EVERY ATTRIBUTE
public Map<FilterGroup, List<Filter>> getGroupedFilters() {
Map<FilterGroup, List<Filter>> grouppedFilters = new HashMap<>();
for (Filter filter : filters ) {
if(!grouppedFilters.containsKey(filter.getGroup())) {
grouppedFilters.put(filter.getGroup(), new ArrayList<>());
}
grouppedFilters.get(filter.getGroup()).add(filter);
}
return grouppedFilters;
}
}

推荐答案
由于Spring Data Commons jar不兼容，可能会出现此问题和Spring Data JPA罐子。请使用 mvn dependency：tree 命令检查这一点。
This issue might be arising due to an incompatibility of your Spring Data Commons jar and Spring Data JPA jars. Please check this using mvn dependency:tree command.
